SPECIFICATION forming part of Letters Patent No. 4473149, dated March 3, 1891.

Application filed May 7, 1890. Serial No. 350,902. (No model.)

To all whom, it may concern.-

.Be it known that LTHoMAs-C. IIARGRAVE, a citizen of the United States, residing at Minneapolis, in the county of Ilennepin and State 5 of Minnesota, have invented certain new and useful Improvements in Matrix-lllahing Machines; and I do herebydeclare the following to bc a full, clear, and'exaot description of the invention, such as will "enable others skilled in the art to which it appertains to make-and use the same.

This invention relatesto machines for making matrices for stereotypes by the consecutive indentation of the various characters 1 5 constituting the matter to be reproduced into a sheet, strip, or slab of pasteboard, papiermache, blotting paper, wood, or other plastic material. v

This invention embodies an improvement on the matrix-making machine shown and described-in my application, Serial No. 335,067,

filed December 26, 1889.

.Tlhe object of the same is to materially f cheapcn the cost of the machine by introducz 5 ing, wherever possible, straight work for the cylindrical and toothed arrangements involved in the disks, cogs, serrated edges, &c., of the machine disclosed in the above application, and by considerably reducing the num- 0 berof parts.

The invention relates more specifically to'the.

die-selecting device, including the die or punch carrier and the means for actuating the same'to bring the punch of the desired character to the impression-pdint, to the lettor-spacing device or the device for feeding the matrix-carriage along before each impres- $1011 or indentation sufficiently for the character to be impressed, and the impression or 0 indenting device.

In the present invention I have substituted for the shifting and rotating die-wheel in my former constflrction a die-carrier movable longitudinall y of the machine and provided with (lie-containing channels, each carrying a row of separate dies, which rows by-the key lever are shifted transversely to the longitudinal movement of the die-carrier, 3y these two movements i am enabled to carry anyde'sircd die opposite the indenting-point. This construction, by eliminating the die-Wheel and cogs for imparting motion thereto, enables me to introduce straight work throughout for these parts, and the dies can be produced more cheaply than when. seated onthe disk, and have, moreover, the advantage of ready interchangeability. I also reduce the motion of the lever considerably by reducing the character-board in size, and at the same time preserve allthe accuracy of the larger char- 6o acter-board by connecting the key-lever for selecting the characters with a'pointer or needle extending over the character-board on which the characters are more compactly arranged. The work of the operation is thus 6 made less tiresome, being reduced to a wrist-' motion only. Moreover, I substitute for the pawl and serrated strip for advancing the matrix-carriage step by step for letter-spacing a plain strip and a sliding clutch-block so arranged as to grip the strip on its forward movement and to release it onits return, ready for the next spacing operation. I have also materially simplified the construction of the arm which controls the extent of letter-spac- Other features of my invention will be pointed out in the specification and covered in the claims.

In order to explain my invention more fully, I will nowgive a'detailed description of a machine embodying-what' I consider the best form of carrying the said invention into effect.

Figs. 2 and 2* are detail views illustrating the relation of the key-lever to the pointer; Fig. 8, a vertical transverse section on line on .r, Fig. 1, looking in the direction of the arrow m; Fig. 4, a rear elevation partly in section; Fig-5, an end View of the matrix-carriageg Fig. 6, a detail view of the mechanism for adjusting the letter-spacing; Fig. 6, a View of 'the compound "spacing-plate developed into a plane; Fig. 7, a detail front elevation of the punch or die carrier; Figs. 8, 9, and 10, detail Views of the said die-carrier;

Figs. 11 11, i3, and 14, def-ail views of the letter-spacing. device, and Fig. 15 an iso' vided with a stud A rising therefrom and encircled by a hub A held in place by headed screw a, whose head projects beyond the stud and bears down on the upper edge of the said hub, which is preferably undercut or rabbeted to make the top of thescrew-headflush with the upper edge of the hub, as shown. An arm a, extending horizontally outward from the hub A has hinged to it at a? the horizontall y-swin gin g key-lever A extending forward under the flaring or inclined character-board A, andabove the notched spacing-plate A preferably in the forth of acompound'plate, the one. plate having uniform notches and the other sliding with respect to the sarne and having variable step-shaped notches for the purpose of adyustin g thespac a carrying the spring-sin notch opposite the sen ingt'o the character selected, all as set forthin my previous applic'atior shown in Fig. 6. The keyd ever is prr ita the boss a knob or handlea the sin to impinge against the co the key lever has closing a circuit for i as set forth in the r said former application the upon being swung around horizontally to totate a die-wheel to bring the desired character on its periphery into printin' positiou,

suitable gearing being interposed between the said leverand die-wheel. This die-wheel was also capable of shifting upon its bearings y to bring one or the other of a number of an is made toengage with one or the other of a" nular rows of characters into line with the printing position, the" shifting being performed by a mechanism substantially the same as that herein ,employed for-longitudinally shifting the die-carrier O, forming part 0t my present invention, and which mechanism consists, essentially, of the forked arm B, attached to the lever B B pivoted to the table B'iat b'fland whose upper arm 13 is made elastic and carries a pin b whose lower end ndinber 0f perforations b b b 11 according asoneor the pth'er row of dies is to be brought into line with the indenting-point.

One of the objects of my present invention- ;the machine.

has been to substitute a device for the above rotary and shifting die-wheel, in which the number of parts' are considerably'reduced,

while the cogs and round surfaces are entirely avoided and straight work substituted.

For this purpose I have devised the following construction: The die-carrier 0 contains a number of die-containing channels, in the present caseopen at top and bottom, as shown, and consistsof a number of parallel vertical plates 0, arranged transversely of the bed of These plates 0, five in num-' her, are removably secured to two end bl'ocks C C by suitable tongues or tenons on theplates 0, fitting into. mortises' in the end blocks, the exterior piates being held in place by screws or-otherwise, all as shown particularly in Fig.5. 2 and 7. The plates-Gare provided with the horizontal ribs dead the top flanges c for the purpose of guiding and supporting the dies or punches 0, provided with nicks to correspond to the ribs andvfianges.

.One of the outer plates 0 is provided with a dovetail orother guide c, as shown, whose office is to hold and guide the die-shifter D,

and which is shown'in detail in Fig-1 5. The

ribs c. and flanges 0' also serve to guide the tongues d of the die-shifter, referr'ed'to below. 1

Thedie-shifter consists of-the vertical body d,havi'ng the two arms tid', which extend over the topof thed'ie-carri'er 0, each arm having a number of tongues (1 corresponding to the number'of slots in thedie-ca'rrier and extend- 'ing down into the same, as shown in Fig. 3,

to embrace the line of type in eachchannel".

From the vertical bodyd extends the bracket. f -preferably in the shape of a fork, as shown, and from the arm a on the hub Aex't'ends downwardly the stud d, engaging the-forked bracket of, whereby w'henthe key-lever A is swung around the rows of dies in the slats ofthe die-carrier are moved transversely.

It will be noted that by having the die- :hannels and also thGdlB-Slllflfll open at top and bottom, as in my preferred construction shown, I gain the important advantage of permitting the plunger which forces the dies into the matriie-blank, and which will be described farther on, to act directly against the ends of the dies, whereby the great pressure necessary to produce a sufficient indentation .can be obtained. This resultc'ould not be obtained if'the die-channels and shifter were not open at both top and bottom. This arrangement also enables me to place the (lies with their indenting-faces downward, whereby I am enabled'to provide a very simple ,1!- rangement of the support for the matrixblank-and to keep the die-faces freefrom dust.

' For the purpose of making the die-carrier capable of longitudinal orto-an-d-fro movement to bring one or the other row of dies into indenting position, I provide the end blocks-G C with dovetails engaging similar grooves ins'tandards C rising from the bed 447,449 I p e of the machine, and I attach the ends of the prongs b offthe forked arm B, already described, to these end blocks.

It will be noted that the character-board A in the present instance is considerably reduced in size, extending over only about onehalf the width of the table 13 the characters being arranged thereon more compactly-for exampleby distributing the letters, numerals,

and punctu'ation marks each over two rows,

' which is engaged or embraced by the sleeve b forming part of the pointer B mounted on the character-hoard, and which, for thc purpose of holding said pointer steady, ex-

tends a considerable'distance beyond the same at both sides.' Secured to the sleeve Z2 is the fork b, extending downwardly and straddling the key-lever, whereby motion is imparted to the pointer from the latter and the desired character may be readily selected. The key- I lever and pointer are thus loosely connected,

so that the key-lever, while-adapted to. carry the pointer over the key-board, may still be depressed at any point.

Where the character-board is arranged at one sideof the machine, as in the present instance, I provide the arm a, which carries the key-lever, with a spur a from which the stud d already referred to, extends.

The operation of the parts thus far described is similar to that in my aforesaid application-that is to say, by causing thepin b of the arm 13 to engage one or the other of the perforations b h, the, I' place one or the other row of dies 0 into line for indenting.

Then by swinging the'key-lever to one or the other point on the character-board A, I cause the stud (l engaging with the bracket LP, to-

carry the die-shifter along to bring the die corresponding to the desired character opposite the indenting-point, to be acted upon by the indenting mechanism to-be described farther on. 4

The arrangement of the character-board with thepointer extending across the same enables me tojconsiderably reduce its size,

and thereby reduce theextent of movement of the arm of the operator.

The operation of the machine is thus rendered less tiresome.

. The Zettensp'ac-mg devz-ce.As in my former "machine,-I,provide a matrix-carriage E, carrying two rollers E E for carrying and feeding the matrix-blank line by line, the upper roller E being yieldingly forced toward the 'lower rollerby spring-bearings, and the carriage being guided by a dovetail e and a corresponding groove. The line-spacing is here again performed by means of a ratchet viheel 8', attached to the end of the journal ofthe roller E, (see Fig, 5,) actuated step'by step by the pawl-lever 6 which is forced back against the stress of spring 6 by the impingement of its upper arm against the-incline e Fig. 2, at each return of the carriage to the initial position. A shaftF, mountedin standards ff, rising from the bed of the machine, is provided atone end with an arm F,urged upwardly by a spring f against a flangef 0n a sliding .piece, preferably in the form of a sleeve F encircling the hub A and normally held upward by spring f Itis in the novel arrangement of the device for moving this carriage forward preparatoryto the in- 1 feed or letter-spacing that my improvement in this part of the machine, whichwill now. be described, consists, and for this special reference is bad to Figs. 6 and 11 to '14. At the rear end the vibratory shaft F is provided with a depending arm F The matrix-carriage E is provided at its rear face purpose with the horizontal flanged rib E preferably having the upwardly and downwardly extending flanges e 'e and which is embraced bya sliding frictional clutch --bloclr- F3, having grooves to correspond to the flanges e a and in the present instance having 'journaled therein the dog'F, whose journal is cut away or cam-shaped, as at f*, to preserve the continuity of the groove, as best shown in Figs. 12 andl. A spring F, whose motion is preferably limited byan abutment f tends to force the sliding block F in the direction of the arrow 2 and toward thearm F The operation of these parts is as follows: When the arm F is depressed by the depression of key.- lever A" and intermediate parts, the arm F is turned in the directionv of the arrow, Fig. 11, and by impinging against the dog F the journal thereof is first turned, so as to cause the cam-surface f to bind against the rib E lhe further movement of the arm F then carries the block F and with it the rib E to which it is now locked, and the car: riage, along sufficiently for the spacing of one letter. Upon 'releasing'the key-leverthe-arm E flies back and the spring. F slides the block F which is now' released or unlocked, back to its initial point, while the carriage.

remains in its advanced position. The car-- riage is thus fed forward one step at each de pression of the keylever, and the extent of its forward feed can-be regulated with perfec't accuracy and nicety byt-he extent of depression ofthe arm F. This result marks 9.

great improvement overthe-lpawl and serrated=edge employed in the machine shown.

in my aforesaid application,- inasmuch as there must always be some lost motion in such a construction however fine the serrations are made. My presentspacing device, moreover, possesses the important advantage f that the omission of the serrations. on the rib that the same is provided with a movable part,

which carries the carriage forward by friction when the carriage is urged in one direction'and releases the same on the return of the carriage.

Turning: now .to Fig. 6, it will be seen that the arm F", which governs the extent of feed of the carriage, is made adjustable, so as to bring the contact-point f, which bears up against the flange 1 of the sliding piece F nearer to or farther from the pivotal point or shaft F. For this purpose the said arm F passes through a slot in the shaft F, being held in any position of' adjustment by a setscrew f By this arrangement of the, arm F, which, it will be noted,is far simpler than the construction for the same purpose in my aforesaid patent, I still further reduce the number of parts and cost of manufacture.

The indenting device-As in my previous application, I provide a singlecontact-strip G, arranged in proximity to the spacing-plate A and adapted to be struck by the springstud a, as the knob d is depressed after the key-lever has reached "the bottom of one of the notches in said spacing-plate. The circuit is again completed by the circuit'wires G, (deriving their electricity from any suitable source, as indicated at 91,1 the bindingpost G ,theelectro-magnetG",and the bind ingpostG whence the current passes to the keylever by means of the spring G attached to the top of the key-lever, as shown, which in the present invention serves the double purpose of conducting the current to the lever and of holding it normally raised to break the circuit.

For the purpose of enabling the key-lever to readily turn on the pivot or stud the' keylever is provided with the rounded bearing orbutton b and thespring is secured thereto by the beaded pin Z2 loosely passing through a hole in the end of the spring. This arrangement involves an improvement over my former construction, inasmuch as one spring here takes the place and performs the functions of the two in the said former construction.

An armature l.l,.attached to the arm H, pivoted in the bracket 11 and normally held upward by the spring 72, operates the plunger l'lithrough the medium of the pitman h,

. ters Patent. is 7 every time the magnet G' is energized through the depression of the key-lever and knob a The particulandie which is at the indenting point is then depressed and forced against and into the m atrix-blank; The means which permit this depression of the selected die with respect to the die-carrier constitute a part of my present invention and are as follows, special reference being had to Figs. 7,

8, 9, and 10.

Each one of the ribbed plates 0' is provided at the point which when the die-carrier is properly shifted will come opposite the indenting-point (in the present case at the mid dle of the plates) with a vertical slot 0 lVithin this slot an inwardly-extending pin, "forming the continuation ofthe rib c, is held upwardly by a spring 0, preferably located ina horizontal slot 0, communicating with the slot 0 It will be readily understood that whenever the die selected is brought forward, so that its nick engages this yielding pin, the die may be depressed into the matrix-blank by It is manifest the descending plunger-H I that many modifications may be devised for this yielding pin and slot without departing from my invention, the -essential features of ,7

which} conceive to be a type-channel .pro-

vided with a rib for r'etai-ning the type, a portion of said rib being held yieldingly-that is to say, made yielding in the direction of pressure in indenting the matrix, and also independent of and disconnected from the plunger which forces the dies into the matrix-blank. It is essential that this die-forcing plungerbe thus independent of the yieldingly-held portion of the rib in order that it may act against the ends of the dies and thus exert the pressure necessary to properly in dent the matrix-blank. 7 Below the die-carrier is located the horizontal stripper-plate I, between which and the bed A the matrix-blank is held, said plate I being provided with a perforation or throat 1: large enough to accommodate any of the dies and directly under the plunger H It will be noted that the space between the stripperplate I and the bed A is made flaring at I opposite the feeding-rolls E E of the matrixcarriage for the purpose of obviating all difficulty of introducing the matrix-blank into said space.

The carriage 'is provided with the index or finger. .1, consisting of a strip of metal suit- 1. In a matrix-making machine, the cornbination of a die-carrier having a die-containing channel open at top and bottom with a die-shifter, also open at .top and bottom, and
